Flex Wallet generates real Ethereum keypairs locally, checking each one against the prefix and suffix you set, until it lands a match. No server ever sees your key.
Each cell searches independently, the same way the real grinder checks candidate addresses. Lime cells are your prefix, violet cells are your suffix, the middle stays random.
A random 256-bit private key comes from your browser's native crypto API, then gets derived into a public key and an Ethereum-format address.
The address is compared against the characters you set on each end. Anything that doesn't match both is thrown away and never stored.
On a match, Flex Wallet stops and hands you the address and private key directly. You choose where they go next: a wallet import, a keystore file, or paper.
Flex Wallet has no account system, no database, no backend that ever sees a private key. The generator is a script running in the tab you're looking at right now.
No network calls during generation. Open dev tools and check the network tab. Nothing goes out while a wallet is being generated.
Open source generator core. The matching logic is auditable, so you can confirm what happens to a discarded candidate before trusting it with a real one.
Works offline. Load the page once, then disconnect entirely. The generator keeps running on your machine alone.
Short prefixes and suffixes are fast enough to run free in your browser tab. Longer combinations benefit from more cores.
No. Keys are generated and matched inside your browser. There's no server endpoint that receives a private key at any point in the flow.
Each added character divides your odds by 16. A 4-character combination might take seconds; an 8-character one can take hours even across multiple cores.
Yes. Forge generates standard secp256k1 Ethereum-format keypairs, so the resulting address is valid on Robinhood Chain and any other EVM-compatible network.
Yes, through CREATE2 salt search on the Custom plan. That searches for a deployment salt rather than a private key, since contract addresses have no key of their own.
